N1KPR Robert W. 'Bob' Betts Shelton, CT QCWA # 37143 Chapter 149

President emeritus Stratford Amateur Radio Club (SARC), club station W1ORS. Also past offices of: Communications Officer, CW and theory (license upgrade) instructor, Secretary, Treasurer, and Historian. I like HF phone/CW, VHF/UHF experimentation, EME R&D, and Radio Astronomy.I am an incurable Telegraph key collector. I've written a few books: learning the skill of Morse code, study techniques, learning problems; also an account of US Railroad Telegraphy from mid-1800s to early 1900s; and a short course for Morse learning (Mneumonic) for the handicapped, and some music books.

I spent 2 years in the US Army attached to the Signal Corps and got to enjoy all the expensive radio equipment they let me play with -- for free. I worked with crypto gear and learned a lot about NORAD, CONAD, SIGINT, COMSEC, Signal Intercept, Surveillance and Countermeasures, and our Air Defense systems. My third year was in Vietnam in the infantry. They took away my crypto cipher book and gave me a rifle. I really preferred the radios over the M16.

I've worked in the electronics, Acoustical, and Mechanical fields since 1963 (variously) as a Designer, Project Engineer, Chief Engineer, Director of Product Design, and VP of Product Design for three corporations, and owned an Engineering Consulting company since 1979; "ACE" American Communications Engineers (ACE).

I'm always building something and experimenting at the bench ... sometimes the stuff works! Sometimes I get pretty blue smoke. However, I have made some pretty good progress developing RF preselector circuits to precondition raw RF directly from the antenna (receive only) and dynamic noise abatement preconditioning circuits -- fun and rewarding. It's truly amazing how much more you can hear when you feed your receiver a healthy diet. Receivers from Watkins-Johnson, Racal, Harris, Collins, ITT/McKay and others really appreciate the preconditioned signals...yumm. Yes, DSP is great, I use an all DSP JRC NRD-545 and some Icom (Government equipment) for receive and my Kenwood TS-940S for transmitting (hard to beat Kenwood transmit audio). But even with DSP, a good preconditioner/preselector makes all the difference in the world. Gee, life is good.

For the time being, I have some of the latest Preconditioner/Preselector, Dynamic Noise Management, and Synchronous (Detector) Demodulation technology posted at my SWL site. Excellent AM and SSB demodulation, along with diversity and ECSS reception makes life much sweeter.
